URGENT - ASUS S400CA Brightness Not Adjusting

Q:URGENT - ASUS S400CA Brightness Not Adjusting

Hi All,

I have an ASUS S400CA running Windows 8.1 (64 bit) and I am having a major issue. When I click Fn + F5/F6 to increase or decrease the brightness, nothing is happening. The slider is stuck beyond a point and the brightness does not change regardless (it is stuck at the highest setting). I have tried to fix this issue by changing brightness settings in the Control Panel, Battery Options, etc. but nothing is working.

How do I fix this issue? Is this is a driver issue? I have tried to find previous versions of the Intel HD Graphics 4000 Driver on the Asus website but only find the one I am using. What should I do? This is urgent!

Thanks so much!

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

On my ASUS Laptop I believe its the ATK utility that controls the Fn key operation. Have a look and see if the ATK utility is available for your model.

She needed a new disk in her system as the old disk was clicking a lot, but I forgot to make Recovery Media, and the product key I cannot get to (it is Windows 8, and the key is embedded in the UEFI.) I rang Asus and they said the only thing I can do is to buy Recovery Media for £42! The old disk is in my Linux system, and it is still readable! Is there a way I can copy the files from the Recovery Partition to a USB drive and then boot from that?

I have ASUS S400CA-UH51T. It has 500GB HDD and 24GB Sandisk U100 SSD as cache drive.I want to know 1) whether it is possible to upgrade ssd to higher specs say 256 GB and clone drive partitions of HDD to SSD and make it bootable?2) if above is not possible, can we clone drive partitions of HDD to 256 GB SSD and replace HDD with SSD?

If any one has already attempted in these lines in same machine, I would like to get feed back from them.

A:ASUS S400CA - upgrading to SSD

I guess the easiest would be to install an extra SSD (if you have ports and space) and transfer the OS to that new SSD. Use the original disk for data.

As I thought it may be useful to some one in my shoes, I am posting below what I did. Aim: To change to SSD before switching over to Windows 10. Research: 1)Selection of SSD Search was made for brand and size. After lot of search in may sites regarding performance and comments by users, I decided to go for Samsung. Then I have decided to go for Evo than Pro as Evo has performance nearer to Pro and good value. Then size is decided as 250GB as SSD at US$100 and external WD passport ultra 1TB at US$60 had more working and backup space than Evo 500GB at US$165. 2) Method of change to SSD Whether first migrate data to SSD or Change over to SSD and then migrate data or change over to SSD and install new windows 8.1. As original installation was windows 8 and then it was upgraded to windows 8.1, factory reset leads to windows 8 only. Further 30 months use laptop with various software install and uninstall, I thought it is better to go for new installation of windows after putting SSD. After browsing, I found that this is possible as key for windows 8 is stored in UEFI BIOS. However in case any problem crops up, I wanted to go for old installation. Hence after lot of research, decided to for free Macrium reflect to do backup image and rescue USB Stick. Then made image and rescue disk. Then I downloaded windows 8.1 ISO using Create installation media for Windows 8.1. I mounted ISO and copied files to fat32 formatted USB stick of 4GB. Process of installing SSD an... Read more

After reading lot of issues in net for last two days, I upgraded all ASUS software and drivers from ASUS support site first. Specially Express cache software needs to be upgraded before upgrading to 8.1 as per ASUS site.Then I started early morning to update as to avoid rush in downloading. I followed procedures available elsewhere to start update from MS stores. It took 15 minutes to download and another 15 minutes for setting before first reboot. During this install program said about adding language support after install only is possible and asked whether want to continue or stop. I opted continue.It did 7 times reboot and in that 3 times showed percentage progress like setting up, setting pc settings and setting a few more things. From first reboot to final, it took 60 minutes. Total duration 90 minutes.Previously installed start8 button was not working.Needed to remove install other start8 button program.Shortcut arrows was removed by me using regedit. That I had to do it again.It has not allowed use of gadgets already installed. uninstalled and used other from this siteWinAero: Downloads / Tools by other people / Desktop gadgets and sidebar for Windows 8.1.Still working more.

I have an Asus VivoBook S400CA that I was thinking about selling. I got it for Christmas. It has never had a virus, and it's in perfect condition. Everything works great. I'm going to sell it with a stylus I got for it, along with the charger. I'm selling it because it's not the laptop for me.

Does anyone know how much I could get for it?

I might also include a detached CD-drive I got from Best Buy... I think it was like, 60 bucks. I've used it once or twice, and I won't be needing it when I get rid of this laptop.

A:Appraisal - Asus VivoBook S400CA

Depends highly on what specs it has. CNET says the price range is $695 - $1142.

Considering this laptop is used, has 6mths warranty left, and isn't factory defaulted (I highly recommend doing this, we can help), I'd be looking at $550 - $950 max as a private sale.

I have used the Asus backtracker application to create the USB recovery partition successfully but when I try to boot from that partition, the process starts up and almost immediately I get this weird error stating [Error] fac phase error (get error = 99) and "ERROR" in large red letters across the whole screen.

I cannot find any explanation as to what this might be. Can anybody help??

I have Dell venue 8 pro. I have seen in forums that it will support Miracast. Whether all windows 8.1 machines/or machines with windows 8 upgraded to windows 8.1 will support miracast? Or is it machine specific?If so how to find out whether ASUS S400CA with windows 8.1 will support miracast?

BSOD occurs frequently in my ASUS S400CA laptop. It is having i5-3317U,8gbram with windows 8. I get error as BAD_POOL_HEADER(tcpip.sys). I am attaching SF Diagnostic tool output. Kindly help me in solving this.

A:BSOD in My ASUS S400CA- BAD_POOL_HEADER(tcpip.sys)

Sorry for the delay in responding. There just aren't that many people who do BSOD analysis, so at times we get a bit overwhelmed!

SSD's were temperamental when they first came out, but their reliability has improved greatly over the last year or two. There are 2 things that MUST be checked on systems with BSOD's and SSD's:

1) That the SSD firmware is the latest available for the SSD2) That the storage controller drivers on the motherboard are the most recent. They must date from late 2012 or later. This is ALL controllers, not just the one that the SSD is attached to.

I'm uncertain about the compatibility of the RAM disk with Win8. Please verify with the manufacturer that your version is compatible with Win8. RAMDisk - Software - Server Memory Products & Services - Dataram They state that v4.0.0 and higher is Win8 compatible.

I suspect your NetWorx program as it was the only 3rd party driver that I spotted in the stack text of the memory dumps (it only showed up once) - and 3 of the 4 memory dumps point to network components. Please uninstall it to see if that stops the BSOD's.

Please update these older drivers. Links are included to assist in looking up the source of the drivers. If unable to find an update, please remove (un-install) the program responsible for that driver. DO NOT manually delete/rename the driver as it may make the system unbootable! :

since i bought my new laptop 2 weeks ago i havent been able to adjust my laptop's screen brightness, it is at it's maximum and the keys do not adjust it i have even tried doing it from the settings but still it doesnt work. Please help the brightness is affecting my eyes

I have a NIVIDIA RIVA TNT2 MODEL 64P monitor with Windows XP installed. The brightness, color etc. on the monitor seem to be at the max but all images/pictures/movie files etc are very dark. Is there any other way to adjust the brightness on the monitor?

A:Adjusting Monitor Brightness

I think that's just your video card type. If your monitor is old and this has been gradually getting worse then it could be going. You can usually adjust the brightness with your video card settings.

Right click desktop, choose properties, settings, advanced. You may have to try a few of the tabs to find the controls.

Yet: it's not working. I've also have a problem booting up games. Even the simplest of games (as the netbook is low-spec) are either not booting up, or they show errors about not being able to access the video card or so. I wonder whether these issues have something to do with the brightness settings.

I'd appreciate any input from you guys

Cheers

A:New laptop not adjusting brightness

Well issue is that your graphics cards drivers are't installed, nor detected! So you are stuck with Basic Display Adapter Drivers

I had a look at the specs and it says "Integrated Intel? HD Graphics" which isn't helpful as there are different models of the Integrated Intel? HD Graphics

The issue is the brightness will rapidly adjust itself intermittently. This is a new problem, Im not sure if there is any settings I can adjust or whatnot before taking it in for repair. Any help is appreciated!

A:Issue with brightness self-adjusting

Is there a hotkey button to adjust the brightness on the laptop? If so maybe it is stuck or sticking.EDIT: My sister has the same laptop try holding the Fn button and tapping the F7 and F8 buttons to adjust the brightness. Those buttons might be sticking causing the issue.

I've recently got a new computer laptop with Windows 7 and the first thing I noticed that the screen is much brighter (and maybe more saturated) than my previous laptop (with Windows XP). First I thought it was my laptop, but then I saw an other computer with Windows 7, and the screen there is very bright too. I searched the net and I see that there are more people complaining about the brightness on Windows 7.I understand that I can set the screen brightness, but it seems like a fact that the "default" brightness on Windows 7 is way brighter than on Windows XP. Some people are probably accustomed to this, but to me it's too much. I can decrease the brightness with the laptopl's controls on the keyboard, but I think that's not the way to go - I think I should look at the Windows 7 configuration. I could go to the ATI Catalyst, but is there an other way? Is the Calibration tool the only option?

And the second question, if this is a common problem, maybe there are some known settings that would take Windows 7 brightness closer to Windows XP and earlier versions?

A:Adjusting Windows 7 brightness - what's the best way?

If these are new laptops then, yes they will be brighter then older computers. But it has nothing to do with Windows. It has to do with the display themselves. A lot of the new LCDs on modern laptops are brighter quite a bit brighter then previous generations in part, moving to LEDs for the backlight.

well when my laptop is plugged in it shows maxiumum brightness, but when its not plugged in it become brighter, yet brightness setting shows in the middle, for not plugged in, how can i get the plugged in brightness to equal unplugged brightness, and I have tried changing power settings.

A:Screen Brightness adjusting help

First of all, please specify maker and model of your laptop. Some vendors could have their own third party replacements for some functions.

Also, please go to Control Panel - Power Options - on the right side of your current active power plan select "Change plan settings" - in the next window click "Change ADVANCED power settings" - then navigate to - Display - Display brightness and check percentage.

i cant get the function keys for the adjusting of brightness of my laptop screen. i can adjust it when it starts up but when the welcome message of windows xp starts i cant adjust it anymore. it's very annoying since i have to restart my laptop just to adjust the brightness using the function keys. anyone can help? please thanks.

I recently upgraded from WIN98SE to WINXP. Before the upgrade I used to go into my Display settings to adjust the brightness on my monitor through the video card, but now through XP I cannot find that function. My video card is a Nvidia Riva TNT2 64MB card. I have a brightness adjustment in the monitor settings, but that is already adjusted at 100% and I need to adjust up a little bit more. Does that make sense? Does someone know where I can find this now that I am on XP?

A:Adjusting Brightness in Display Driver

Uninstall your NVidia display adapter. Run one of these to be sure all the driver files are removed: Driver Cleaner Professional or Nasty File Remover.

Then, install the most recent driver:

http://www.nvidia.com/content/drivers/drivers.asp

You'll find color, brightness, gamma adjustments in the advanced display properties and a separate adjustment for DirectX overlays, such as video player windows.

I have a problem with my dell inspiron m301z laptop,
Whenever there is something dark on my display ( this could be a picture or a website or something else) my brightness automatically adjusts to that environment. So its like the brightness is adjusting automatically depending on the virtual environment. I looked up the forum for similiar problems and tried some things with the power options and stuff but couldnt not fix it..

However this does not happen when the adapter is plugged in, everything stays equal all the time,

Thank you guys.

So you are referring to a difference in behaviour when running on battery power versus mains power?

After upgrading the OS to windows 10, the fn keys (f9 and f10) for adjusting the screen brightness are not working. I have already updated the driver of the keyboard to the latest version and there is no problem in ajusting the screen brightness in the display setting panel. Please help.

I purchased a new computer the other day and it is running Windows 10 Home. One thing that's annoying me is that when I adjust the screen brightness through Control Panel it keeps getting undone. I don't want to squint when I look at my screen. I keep having to increase the brightness all the time. How can I set the brightness and have it stick? Thanks.

I was adjusting my battery settings on my laptop and now my screen has gone much darker. I cant seem to locate a brightness adjustment in the control panel. Can anyone make a suggestion? The laptop is a lennovo ibm thinkpad.

A:Solved: adjusting screen brightness

actually, i think i just figured it out. I had changed the setting to maximum battery life. Just switched it back to maximum performance and issue went away

What happens is, whenever I adjust my monitor's brightness (from its physical buttons) the screen turns black. However the monitor is still on, the LED is still green and the computer is still responsive, the screen just turns black.

I can use the computer just fine, as long as I don't try to adjust anything. If I do want to change something, I have to change the values a little, then restart, change them again, restart until I have the values I want. This problem appeared when I tried to adjust the brightness by keeping the + button pressed down, so it increased quickly.

Is this indicative of a dying monitor ? It is pretty old, it's an LG L1750SQ, 17 inch LCD, it's over 4 years old. Also, I do not believe the video card to the problem, since it stays pretty cool, it has a good heatsink on it.

I just got the HP Pavilion 27xi IPS LED Backlit Monitor at work, working on a computer running Windows 10. I'm pretty tech-saavy, but I cannot figure out how to adjust the brightness! I've tried the F9/F10 function; doesn't work. I then thought it might be an issue with the driver, so I went to Settings -> Displays -> Advanced Display Settings -> Display Adaptor Properties -> Monitor (tab) -> Properties -> Driver (tab) -> Update Driver but got the "The best driver software for your device is already installed" message. Under the Settings -> Displays screen, there's no option for adapting the brightness and I've scoured the forums, but none of the solutions presented are working. Should I manually install an older version of the driver software? Any other potential solutions?

I recently got an ASUS VN248h-p IPS monitor and I notice the brightness shifts with what looks like a blue or light bar of shade that goes up the screen when I view the monitor from down to up. Is this normal?

Here are pictures:

A:Asus VN248h-p ips brightness issue, is this normal?

IPS panels generally provide better viewing angles (compared to other display technologies), it's highly unlikely that you will ever be using the monitor by looking down at that sharp of an angle on it.

Although, I checked the monitor's splash page on the ASUS website and they say this:ASUS said:

Hi,I own an ASUS G56JK notebook, newly installed windows 8.1 64bit.I can not adjust my brightness using keyboard shortcuts or using system tools. And as you can see in the screenshot, brightness control is "unavailable". I have installed all the drivers including VGA driver. I have tried updating monitor and microsoft basic display adapter in device manager.

I have one more problem, I have updated my BIOS to 202, the latest version, and I cannot find power options. I want to set an automatic power-on timer for my laptop.

I've noticed, today, that I'm suddenly unable to adjust my screen brightness. I have read half a dozen threads reporting the same problem; I tried all the solutions therein (from updating the driver and reverting to the most basic one to manually changing power configurations) and nothing worked. Unlike the vast majority of users who had this problem, this hasn't happened following an update to windows 8.1 (which I did several months ago -- and the adjust was working fine after that).

This might give you a hint:

* As I try to adjust it using the fn key (as I had always done previously), brightness goes up or down just one level -- and that just 'cosmetically', as in fact nothing changes. The indicator gets stuck approximately in the middle of the bar, unable to reach the extremes.

* There is more: on power management, I chose the lowest possible level of brightness when working on battery, just to see what would happen. I then disconnected my laptop from main power, and... the brightness indicator did go down to the lowest level, YET brightness remained unaltered in fact.

Anyone, please??

A:unable to adjust screen brightness - windows 8.1 - ASUS

try turning off Adaptive Display in advanced settings under power management

I'm recently planning to build my own PC with a low budget of US$600 (including chassis, PSU, M/B, ODD, HDD, CPU, GPU...).And I've chosen all of the parts but stuck on the M/B part, which I'm not even sure what brand of'em should I get. Many out there are say'in ASUS is the 'World Best M/B'. I realizes that, but also realizing the cost of an ASUS M/B, is a lot more pricey than GIGABYTE & MSI. And should I get a mATX or ATX? Some folks are say'in that the mATX have short lifespan. It's that true??

Hence, with those questions above scrambling in my mind I'm here and hope you all will provide me some precious opinion and recommendations.

That blue screen error is because the Windows disc you're using doesn't have the correct drivers to support your hard drive. If you have a floppy drive, you can download the Mass Storage drivers for your mother board to a floppy disc and press F6 when prompted by Windows setup.

You could also go into your BIOS setup and change your SATA operation to Compatible mode (may be worded differently) for the installation. Or you can download the storage drivers and slipstream them into your install disc with nlite

Hello, first of all I'm not that computer savy, so please keep this in mind! I can google my way around most problems, learning as I go, but this one is giving me trouble. Also, English isn't my first language so I might use imprecise terms, sorry in advance about that.

I bought this new laptop last week, the Asus N551JK-DM193H, and I'm pretty happy with it. It came with Windows 8.1. I noticed yesterday that, all of a sudden, the fn+screen brightness keys didn't work anymore. There has been a graphic driver update, I can't remember if I was able to adjust the brightness right after that honestly.I found this forum while looking for a solution, I've tried rolling back the driver but it didn't do anything. Trying to change the brightness manually from the power options or the charm bar isn't working, either.Also, sometimes the screen dims a bit and then gets back to the normal brighntess.It's quite subtle, but noticeable if I'm on a page/program with lots of white space.

I have pretty delicate eyes, so not being able to adjust the brightness+intense work using the laptop is already becoming a problem. I hope you can help me, and thanks in advance!

(I hope I have posted this in the right category,since I saw similar issues were here)

Have you tried doing a proper full restart (not a shut down and reboot).You could try 'System Restore' to a date when you know it was working.Finally, as its so knew and if you haven't much installed then doing a factory reset is an option. That will take it all back to day 1 condition.

Beginning today, I opened my laptop from sleep and noticed the display was at its lowest brightness setting. I then tried to restart it to see if that would solve it, no luck. I did some googling and found out it could be a problem with the graphics driver. I then disabled it and enabled it. Now the brightness is at its max settings.

The function (FN) + F4, F5 (the keys to adjust the brightness settings) do nothing. The brightness status will show up on the screen and only change 1 or 2 notches.

I then realized I should have a way to adjust the brightness via the Power Settings in the Control Panel. I even confirmed this with a friend. I should have the sliders to adjust the brightness but I do not. It's very strange.

This is the screenshot from my friend:

Hello, I have a minor problem happening. When I play certain games in windowed mode the brightness of the game will make my desktop of the same brightness.
